I don't really understand what you're trying to do here.
If you are really going to "delete" a table - i.e. drop the table completely - then you need to decide what to do with any data in the table (remove it or move it somewhere else) and also what to do with any related data e.g. data in tables that have foreign keys to your table (do you want to cascade the deletion to these child tables?).
If you really mean that you just want to delete individual records from your parent table, then you still need to decide what to do about any child records with foreign keys i.e. you need to look at the foreign keys that depend on the main table and figure out what to do with the related data if you delete the parent records.
